She wrote in the caption: "Last gratuitous bday post: Thank you to everyone who sent me treats and made my day SO SPECIAL!!! Love you all. And to all my friends who didn't, you're dead to me."

As her caption suggests, Lively posted a number of other Instagrams shamelessly celebrating her birthday.

The actress enjoyed what looks like a pretty low-key dinner — albeit one that included her celebrity friend Anna Kendrick — and had a gorgeous-looking cake topped with sparklers. She compared the event to a "super sweet sixteen."
